Nutter Bypass Tip

I just want to put out there to anyone who had this problem. When doing the bypass there is actually 2 sets of Orange and Purple wires. The 2 wires that you actually need to cut go into the firewall right behind the engine in the center of the firewall and the other 2 wires go into the firewall on the drivers side where the fuse box is inside the jeep underdash. What i have found is the Orange wire going into firewall to fuse panel still controls the ignition but won't work cause it goes to computer and when you cut that it is still like running with the computer and it is pointless in cutting it. The other Purple wire that is also at the fuse panel goes to the Temp guage. So the two wires you need for a true nutter bypass are the two wires that go into firewall right behind the engine. Please make a note of that.

I had trouble with this at first but quickly discovered this little problem.
So if im alone on this then disregard this message and im a doof

What do women and Jeeps have in common? The harder you ride them the more money it's going to cost you.

This is the tip I was looking for. Thank you. According to the directions, the junction is between the battery and the valve cover, but I didn't see anything there. ( I havne't had time to open up the harness.)

This Jeep is going to get Nuttered and Carbed (Motorcraft) and I'm the kind of dog that like to make one change at a time to be sure everything is dialed in from one before moving to the other. So, I'm wondering if anyone has a hint on which one I should do first.

Or should I just Man Up and do them both at once and struggle with the fall out? My concern is that it won't run right (or at all) and I won't know which one I messed up.

I'm leaning towards the Nutter first.
